When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 5a - 7a = -3a + y - 3 for a in terms of y.
| -1\(\frac{1}{8}\)y - \(\frac{3}{4}\) | |
| 1\(\frac{2}{3}\)y + \(\frac{2}{9}\) | |
| y - \(\frac{3}{8}\) | |
| 1\(\frac{2}{5}\)y - \(\frac{2}{5}\) |
